PROBLEM TO BE SOLVED: To provide an optical transmission device capable of grasping the intensity of an optical signal of one wavelength to be selectively received by a transponder function section in an input optical multiplexed signal.SOLUTION: An optical channel monitor function section inputs an optical multiplexed signal obtained by multiplexing a plurality of optical signals of different wavelength, and acquires optical multiplexed signal spectrum information showing the intensity of each of the optical signals included in the optical multiplexed signal. A transponder function section inputs the optical multiplexed signal, and acquires desired information by selectively receiving one optical signal from the optical multiplexed signal, and acquires the intensity of the optical multiplexed signal. A monitor control section calculates the intensity of one optical signal selectively received by the transponder function section on the basis of the optical multiplexed spectrum information acquired by the optical channel monitor function section and the intensity of the optical multiplexed signal acquired by the transponder function section. |
